Can't build using docker : ./clang.bazelrc: Permission denied

[rbahegne]

Envoy build fail with /source/ci/../bazel/setup_clang.sh: line 22: ./clang.bazelrc: Permission denied

Description:
I'm trying to build envoy on Rocky linux 8

Repro steps:

cd
git clone https://github.com/envoyproxy/envoy.git
 cd envoy/
./ci/run_envoy_docker.sh './ci/do_ci.sh release.server_only'

ouput :

Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.
ENVOY_SRCDIR=/source
ENVOY_BUILD_TARGET=//source/exe:envoy-static
ENVOY_BUILD_ARCH=x86_64
Setting test_tmpdir to /build/tmp.
/source/ci/../bazel/setup_clang.sh: line 22: ./clang.bazelrc: Permission denied

Note: Since Docker is not available on Rocky it use automatically the docker emulation by podman, but i don't think it is related.
My user is called Rocky and has admin access, envoy is clone in the home directory.

i think this is related to podman

i believe the issue is that the user you are running as inside the container doesnt have permissions to write in the repo directory

run_envoy_docker.sh has some mangling to ensure that the user matches inside/outside the container to ensure the container user can write there
